Abstract

We compared the morphological aspect of glioblastoma-associated microglia/macrophages cells in 15 paired recurrent glioblastomas to check the ability of glioblastoma to recreate its microenvironment. The absolute number of GAMs is lower in normal tissue (21/mm2) than in the isolated tumor cells area (100–112/mm2) than in the solid tumor area (212–220/mm2) (p < 0.01). The morphology of GAMs remained the same in each tumor area with a reduced covered area by cell processes (196 to 216/mm2) than in normal tissue (708/mm2) (p < 0.01). In paired tumors, GAMs morphology remained the same in successive resections and was not modified by the treatments.
